WBINGEB ROLLS FOB CLOTHES W RING-BBS.

Application filed September To all whom it may concern.

Be it known that I, Grosmvr. H. JANm, a citizen of the United States,residing at WVyoming, in the county of Hamilton and btate of Ohio, haveinvented certain new and useful Improvements in Wringer Rolls forClothes Wringers, of which the followin is a specification.

t has been a usual practice heretofore in making clothes wringers torovidethe shafts of the wringer rolls w1th meshin' cog-gears so as todrive one wringer rol shaft from the other wringer roll shaft. This hasbeen done to provide a positive driving connection between the wringerrolls. It has been found in practice that, if the wringer rolls, asheretofore constructed, receive a coating of soapy slime, as happens inthe use of the wringer, the driving wringer roll will, in the absence ofsuch meshing gearing between the wringer roll shafts, fail to affordsuflicient traction for the opposed wringer roll, to rotate the latter,with the result that, if it is attempted to put clothes between thewringer rolls,

the wringer rolls will not grip the clothes to draw the clothes betweenthe wringer rolls, but the driving wringer roll will merely turn withouthaving tractive force either upon the opposed wringer roll or theclothes.

It is the object of my invention to so construct the wringer rolls, asto insure tractive force between them in the absence of mesh- It is thefurther object of my inventionto provide wringer rolls with coactingtractive sections arranged to drive one wringer roll from the otherwringer roll, and, further, to provide the wringer rolls with portionswhose primary function is to maintain drlilving' relation betweencoacting wringer ro s.

The invention will be further readily understood from the followindescription and claims, and from the drawlngs, in which latter:

21 represents a usual frame of a clothes 35 wringer which ma be ofsuitable construction. rin er ro are usually arranged in pairs in t eclothes wringer. Suitable means are provided for imparting rotation toone of t e wringer rolls. These means 00 may be manual means or powerdriven means, as may be desired.

I have shown power driven means comprising a bevel-gear 22, which isdriven for instance by a shaft 23, journaled in a bear- 96 ing 24, andmeshing with bevel-gears 25, 26, normally loose about the shaft of oneof the wringer rolls.

A clutch-collar 28 has spline connection 29 with said shaft, the saidclutch-collar and lot the respective bevel-gears 25, 26, being providedwith the coacting teeth of clutches 31,

' bearings 44 in the frame, and the shaft 45 of the wringer roll 42 isarranged to rotate in bearings 46. The bearings 46 slide in guideways47in the frame. Pressure means are provided for exerting pressurebetween the wringer rolls when wringing clothes.

A spring 48 may be employed to exert this pressure, being shownadjustable by means of a screw 49, threaded in a bearing 50 on across-bar 51 of the frame. The mounting, driving and pressure means maybe of any usual or desired form or construction.

I have dispensed with the usual cog-gears between the wringer rolls. Inorder to insure driving relation between the coacting wringer rolls, Iprovide the wringer rolls with tractive portions which engage each otherto coact for insuring frictional driving relation between" the wringerrolls. These tractive portions may assume different forms, and I haveexemplified five such forms in the drawings. It is obvious that thevarious forms may be employed coactingly, or one form may coact withanother, or one or both ends of the wringer rolls may be provided withmy invention, or

. other changes be made, without departing from the spirit of myinvention within the scope of the appended claims.

Referring to Figs. 1, 2, 3 and 4, I have provided the wringer roll witha tractive section 55, exemplified as arranged about the axis of thewringer roll, andformed in the material of the body, for instance,rubber, of the wringer roll. One of these tractive sections is shownlocated at each end of the wringer-roll. This tractive section orroughened section of the wringer roll is exemplified as recurrentprotuberances or ridges and grooves, arranged about the axis of thewringer roll, at the end or ends of the wringer roll. They form tractivetransmission sections of the rolls to transmit rotation from one of therolls to the other of the rolls.

Referring to Fig; 1, the tractive sections, whatever their form, mayhave shields 57 received thereover, the shields being suitably securedto the frame of the machine. End collars 58 are provided on thewringer-roll. Each of the end collars is shown located on a reducedannular step 60 of the shaft, against an annular shoulder 61 formed byupset, as shown at the roughened or ribbed tractive sections will causerotative tractive transmission from one of the wringer rolls to theother of the wringer rolls, with sufficient force to cause a piece offabric or clothes to be gripped between the wringer rolls and to drawthe same in between the rolls.

When the clothes have been once gripped between the wringer rolls, theclothes act as a medium to cause transmission of rotation from thedriving wringer roll through the clothes to the opposed wringer roll formaintaining rotation of the opposed wringer r011 when once the clotheshave been started between the rolls.

The presence of the clothes causes a relief or separation between thetractive sections and relieves these tractive sections from wear, thetractive sections being preferably protected from contact by the goodsby the shields 57. The principal wear upon the wringer rolls takes placein those portions thereof which are contacted by the clothes,

and serve to express the water from the.

clothes, and, as most of the rotation of the wringer roll takes placewhile clothes are located between the rolls, the driving faces of thetractive sections of the wringer rolls are preserved, and maintenance ofcontact between coacting tractive sections is as-' sured, due to thegreater wear of the expressing portions of the rolls.

I have in Figs. 5 and 6 shown a similar form of tractive section 65 forthe rolls, com prising ribs and spaces between the ribs, similar to theribs and spaces of the tractive transmission section 55, the circleinwhich the crowns or outer peripheries of the ribs is located, being ofgreater diameter than the cylinderof the roll. In this constructiongreater pressure is brought to bear between the tractive sections of therolls when the wringer rolls are in coactin pressure relation, foraifordin additiona tractive force.

In the forms s own in Figs. 1 to 6 inclusive, the tractive sections areshown as integral with the body 53'of the roll, being formed forinstance by forming the mold in which the wringer roll is molded withcounterparts of the ribs and spaces between the ribs, soas to form theribs and the spaces between the ribs, on the rolls at the same time thatthe body of the roll is formed, and of the same material as thematerial, for instance, rubber, of the body of the roll, the whole beingvulcanized together to, form an integral structure.

In the form shown in Figs. 1 to 6 inclusive there is pressure brought tobear between the tractive sections of the coacting rolls to causetractive transmission of rotation from the driving wringer roll to thedriven wringer roll. This pressure is greater in the form shown in Figs.5 and 6. The pressure tends to resiliently flatten or distort thetractive sections one upon the other for enhancing the tractivetransmission, as clearly shown in Figs. 3 and 4, and in Figs. 5 and 6.

I have, in Figs. 7, 8 and 9, shown a further modification, in which thefriction or tractive transmission section of the roll comprises a band75, this band bein shown of slightly greater diameter than t e body 73of the roll. These bands are referably of a softer or more yielding rubr than the rubber of the body of the roll, but are preferably vulcanizedwith the body of the roll, so as to firmly adhere thereto or becomeamalgamated therewith and form an integral structure, one or both endsof the rolls ma be provided with these bands.

lz'hen pressure is applied between the rolls in this exemplification ofmy invention, the friction bands are com ressed upon the respectivebodies of the ro ls for resiliently flattening or distorting the contactportions of said bands and compelling tractive transmission of rotationfrom the driving wringer roll to the driven wringer roll 10 means ofsaid bands. The distortion of t e band is communicated somewhat to thebody of the roll, all as clearly shown in Figs. 7, 8 and 9. In this formalso there is separation between the wringer rolls when the oods havebeen received between the wringer rolls, thereby relieving pressurebetween said friction or tractive transmission sections.

I have, in Figs. 10 and 11, shown a further modification in whichfriction bands 85 are employed which are received in rabbets 86 in theends of the bodies 83 of the'wringer rolls. These bands are preferablyof softer or more yielding rubber than the bodies of the rolls, and arepreferably vulcanized in said rabbets, so as to become amalgamated withsaid bodies, and form an integral structurewith the bodies. Theypreferably extend radially beyond the periphery of the bodies of therolls for having firmer contact when pressure is brought to bear uponthe rolls. One or both ends of the rolls may be provided with saidbands.

The compressive action upon said bands extends into the cylindricalprojection of the rolls and the distortion extends over a great; er areaand to a greater depth radially than in the form shown in Figs. 7, 8 and9, thereby lending additional traction between the rolls, whichdistortion or action of the tractive transmission portion is clearlyindicated in Figs. 10 and 11.

I have in Fig. 12 shown a fornrsimilar to that'shown in Figs. 10 and 11,with this addition, that the bands 95 are provided with peripheralprotuberances 94, shown as ribs and spaces between the ribs, the bandbeing otherwise similar to the band 85, and received in an annularrabbet 96 in the body of the wringer-roll, the expressing section ofwhich is indicated at 99. The band is preferably vulcanized to the bodyto form an integral structure. The resilient protuberances aid in thetractive transmission of rotation between the wringer rolls.
